Answer:
x = 3
y = 4
hey, I am not 100% sure of the certainty of my answers, I am using what I remember about that topic but I do not know if it is right or wrong, I hope I have helped you, I did what I could.
Step-by-step explanation:
-3x + 2y = 23
5x + 2y = -17
X solution:
(you cancel the y)
-3x = 23
5x = -17
(you combine all the values above with those below)
2x = 6
(solve the ecuation normaly)
x = 6/2 = 3
Y solution:
(you replace the x)
-3(3) + 2y = 23
5(3) + 2y = -17
-9 + 2y = 23
15 + 2y = -17
(you combine all the values above with those below)
6 + 4y = 6
(solve the ecuation normaly)
4y = 0
y = 4
(I do not really know if the answer here is 0 or 4 since when passing the 4 to divide it would be 0/4 and I do not understand very well how that is solved)
Answer:
660 nails
Step-by-step explanation:
Take all of john's nails and multiply by 4.4 because 176/40 is 4.4. Multiply 4.4 by the john's other nails. Add the products together and thats your answer.
So burger king offers 10 chicken nuggets for $1.49
1 chicken nugget = price for 10 chicken nugget / 10 chicken nugget
= $1.49 / 10 = $0.15 per nugget (approximated)
Hope that helps!
B > -21 is i think you answer.
